<p>Is lexical_regions_resolve part of the pre-NLL code and bound to go away soon? I'm dabbling around with the expansion() code and have I rather simple patch that cuts the item_bodies check time for the unicode_normalization crate in half by stripping out rules that won't have any effect in further iterations during the fixed point calculation. But just now I noticed that I'm in lexical land, so I wonder whether it's actually worth spending any (more) time on that</p>

<p>It is supposed to be removed at some point, but for now it's always run, whether or not NLL is enabled.</p>

<p><span class="user-mention" data-user-id="158223">@Björn Steinbrink</span> I do expect it to go away but not sure on what schedule. I wouldn't go <em>crazy</em> but if you have simple patches to make improvements, seems good</p>
